To all whom it may concern:

Be it known that we, WILLIAM MARSHALL JEWELL and OMAR HnsTRmN JEWELL, citizens of the United States, residing at Chicago, 111., have invented certain new and useful Improvements in CanOpeners, of which the following is a specification. Our invention relates solely to the class of can openers employing cutting wheels (and particularly those of a portable construction for household use), and isintended primarily to lessen the cost of construction of the one shown in our copending application filed Dec. 31, 1923," Serial Number 683,723; but retaining the essential feature of spring tension or elasticity between the working parts.

In the device herein shown, the driving knurl wheel and the cutter wheel are placed at the opposite end of the handle or close to the bent portion instead of at the free ends of the U; in this way the two sides are used as squeezers to bring the wheels together and the flexibility of the handles thus' formed afiording suficient pressure to cut through the can wall and most seams but yielding, should occasion require, to very heavy scams or obstructions liable to interfere with the turning of the drivingwheel or injure the cutter wheel.

Figure 1 is a top view, illustrating the principal features of construction. Fig. 2 is a part cross section on line 0-0 of Fig. 1. Figures 3, 5, and 7 show some obvious modifications; Fiures 4 and 6 are cross sections on lines and e-e o f Figures 3 and 5 respectively.

In Figure 1 the sides, or handles; 1 and 1' are formed of one piece of spring steel bent in the shape of a U and twisted at right angles at the bend 2 and the intermediate points b to obtain suitable ,flexibility; the spring tension being inwardly so, as .to keep the handles closed when not in use. A flattened ring 3, or other suitable arrangement, may be used to obtain a uniform elastic pressure between the wheels and the can flange and to assist in closing the handles. '56 Tflhe pin 4 prevents this ring from slipping As will be seen in Fig. 2, the handles 1 and 1 at points adjacent to the bend, carry the cutter wheel 5, shoulder screw 6 andnut 7; on one side, and the knurled driving wheel 8, stem 9, turmng bar 10 on the other side, respectively. The dotted lines 11 and 12 represent the top and side wall of the can, respectively.

In the modifications shownin Figs. 3 and 5, the handles 1 and 1 are separate pieces; in Fig. 3 they are rigidly joined by a small piece of spring steel 13 riveted at 14, while in Fig. 5 a swinging joint is formed by turning over one end of the handle 1 at right angle 15 and riveting to one end of the hendle 1 at 1,6.

The construction shown in Fig. 7 is sub stantially the same as that ofFig. 1 with the exception of the use of or extensions and round, instead of flat, spring steel. The round steel is flattened at f and f and drilled at 17 and 18 for the wooden handles knurled driving wheel 8 and shoulder screw 6 respectively. The handles 1 and 1 are roun at 19 and checked down, as shown by dotted lines, dles 20 which are reinforced by metal ferrules 21. The swinging point or bend 22 is also round and same dlameter as at 19.

In Fig. 5 the flexible points I) are elongated to form a curved handle, shown in part; and in Fig. 3 this result is attained by slotting as at points 9, so that the handles will touch, or nearly touch, when the proper tension has been applied to the can flange.

where they enter the wood han- What we believe to be new and desire to secure by Letters Patent is:

1. A portable can opener comprising two movable handles adapted to be held in one hand and joined ad'acent to one end of each handle, a cutter w eel mounted on one of the handles and a driving wheel mounted on the other handle; both of said wheels ing" located adjacent to the closed endsand befiween the joint and the open extended en s.

2. A portable can opener com rising a U- shaped sprin handle, a cutter w eel mounted on one si e and a knurled driving wheel mounted on the other side of said handle adjacentto the bend.

v 3. A. portable can opener comprising a spring handle in the form of a a cutter wheel mounted on one side and a toothed driving wheel mounted on the other side: both of said wheels being located adjacent to the bendand the open ends of the'handle extended sufiiciently to appl the necessary pressure between said 51188 S and the can by clasping in one 1. In.

4. A portable can opener comprisin two movable handles pivoted at one end 0 each handle, a cutter wheel mounted adjacent to the closed end on one of the handles and a 5 driving wheel mounted adjacent to the closed end on the other handle; both of said wheels being located between the pivot and the clasped'ends.

5. A portable can opener comprising two 10 movable handles united at one end of each handle, a cutter wheel and adriving wheel mounted thereon in op osed relation to each other at the closed en s.

In testimony whereof we have aflixed our signatures hereto this seventeenth day of 15 May, 1924.
